 ## Adding a New API Endpoint
 
-1. Define request/response messages in `ldk-server-protos/src/proto/api.proto`
+1. Define request/response messages in `ldk-server-grpc/src/proto/api.proto`
 2. Regenerate protos (see above)
 3. Create handler in `ldk-server/src/api/` (follow existing patterns)
 4. Add route in `ldk-server/src/service.rs`
